The Claim

Protein restriction in lean men induces upregulation of mitochondrial electron transport chain complexes I–IV and downregulation of ATP synthase components in subcutaneous adipose tissue, suggesting mitochondrial uncoupling may contribute to increased energy expenditure.

Source: Dietary protein restriction elevates FGF21 levels and energy requirements to maintain body weight in lean men

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

In lean men, reducing protein intake alters mitochondrial proteins in fat tissue, increasing some components involved in energy production while decreasing others, which may lead to higher energy use.

What the research says

1 study
  1. Study: Dietary protein restriction elevates FGF21 levels and energy requirements to maintain body weight in lean men

    When lean men ate less protein, their bodies burned more energy just to stay the same weight, and their fat cells changed how they make energy—using more parts of the energy machine but less of the part that saves energy, which makes the body burn more calories.
